Ast convinced me that I should really take all the obsessive firearms knowledge I've gathered over my years as an artist and compile it into a tutorial for artists who want to draw guns.

So, here's the first section's (early firearms) draft. Going to be working on and off on this; I'd like comments on usability, length of information (too little, too much, too much tangential stuff that doesn't matter to artists?) etc. Should I be assuming people know what a barrel of a gun is? Things like that. Critiques and comments will help me make this the best guide I can make it!
